In my said copending application, I have disclosed a process and mechanism for treating fabrics and garments, and have shown in the said application, the valve mechanism which forms 5 the subject matter of the present application, as

applied to a garment pressing machine.

The mechanism forming the subject matter of the present application is adapted for use in mixing steam and air for the purposes mentioned in my said copending application, as well as for mix- ZO ing and projecting onto fabrics or garments air or steam and moth repellant or moth-proofing compositions of various types, whereby the composition will saturate the fabrics or garments.

The foregoing are only illustrative uses of the 29 present invention, and the same may be used for many various purposes where the flow of fluids is to be selectively and collectively controlled.

n In the accompanying drawings, I have illustrated one form of my valve mechanism applied to a portion of a garment pressing machine, and it is to be understood that both forms may be so applied or used for other purposes where fluids N are to be admixed and sprayed.

Referring to Fig. 1 of the drawings, the numeral 2 indicates generally a buck or lower member of a garment pressing couple, the other member of which includes a head or movable member 5 supported by lever 3, which is. fulcrumed on a 5 suitable frame and operated by known mechanism, (not shown) such as disclosed in Patent 1,715,115, dated May 28, 1929. The head 5 comprises connected or integral upper and lower walls Ill and l I respectively, enclosing a heating cham- 10 her E2 to which steam is supplied as by a pipe connection I3. The lower wall is formed to provide a distributing space or chamber It for the perforated cover plate 15. The. buck is formed with a heating chamber IE to which steam is sup- 15 plied at any convenient point (not shown) and its upper side is formed to providea receiving chamher I! with a perforated cover plate l8 with a discharge opening or passage 18a, at any conven ient point, to which a pipe i9 is connected to 20, formed to receive a tubular portion 2! of a 5 valve body 22, which, with its connected and as.- sociated parts, constitutes in one form a principal part of the invention mechanism. The lower end of the tubular portion 2| is threaded and screwed into a tapped hole 23 in the lower wall I I, forsupply of air or steam, or a mixture of. air and steam, or other fluids as hereinafter pointed out, to the distributing chamber 14. A gland nut 24 and washer 25 or other suitable packing are provided to seal the valve body where it enters the boss 20. g

In the present illustrative embodiment of the invention, I have shown a steam chamber 26 formed in the'upper portion of the body, to which steam is supplied from the heating chamber I2 through one or more holes 21. g A steam valve seat 28 is formed at the top of a tubular formation 29 in a wall 3%, and a steam nozzle 3| is detachably located (for instance as by a screw connection as shown) in the lower end of the tubular steam passage, with its end properly located, anterior to a throat 32 in the tubular portion 32a of the valve body, which has a Venturi formation for an injector effect, as will appear. A reciprocating valvesupport or valve stem 33 has a face or valve disc 34 of any suitable material cooperating with the valveseat 28, and a guide maybe provided such as the head 35 of a screw 36 which retains the valve disc. The screw head reciprocates within the tubular steam passage 29 below the valve seat and is flattened or channeled on each side to provide for steam passage. The upper end of the valve support or stem 33 is in the form of a sleeve 38 slidably mounted on a stud 39 at the center of a screw cap 48 which closes the upper end of the valve body, and a helical spring 4| is placed about the sleeve and compressed between the screw cap and the valve support to urge the valve to closed position. The valve support or stem 33 has at one side a slot 42 to receive a lug 43 projecting from a stem or shaft 44 which passes through the body,in which it is revolubly mounted, with suitable packing (not shown). One end of the stem valve operating shaft or stem 44 projects from the valve body at one side thereof, and has thereon a short arm 45 (Fig. l) the end of which confronts an arm or lug 45 forming a part of one of the controlling levers, referred to below.

The valve body 22 is formed with a passage 48 leading from a port 48' at one side of the body to the upper end of the Venturi passage 32a. The face 49 of the body about the port is finished off flat to provide aseat for the face 58 of a valve or damper which is pivotally mounted on a pin 52 in a lug 53 on the body. The damper has an integral lug 54, and a helical spring 55 is placed between this lug and another lug or spring socket 56 formed on the upper end of a lever 58, (Figs. 3 to '7), which ispivotally mounted on pin 52 independently of damper 5| and its lug 54.

The valve structure as a whole may vary considerably, the principal features being independently controllable valved ports arranged to supply selectively one fluid or a mixture of several fluids to a passage such as the Venturi passage. The operating means may also vary greatly, but in the construction and arrangement shown in Figs. 1-6, inclusive, such means consists in associated levers having devices to operate the respective valves, or elements connected to the valves, and arranged, for independent or cooperative manipulation, as follows:

The main operating lever 65 is forked at one end providing arms located at opposite sidesof the valve body fulcrumed on the ends of a shaft or pin 4'! which passes through a bearing hole formed in the body below the port 48. The lug or arm 46, above mentioned, is formed integrally on one of the fork arms of the lever 68, and the other fork arm has at its end, adjacent the valve body, at the side opposite to lug 46, a short upwardly projecting lugor arm 6|, one face and the end ofwhich cooperates with lever 58, and the other face or end cooperates with a face 62 of the damper 5i projecting laterally and parallel to the active valve face 58, Thus the lever arm 6| is always located between the lever arm58 and the face or flange 62. Another controlling lever 65, is pivotally connected. at 66 to lever 68, and may be of channel section or have a flange overlying lever 68, to engage one end of a spring 6'! which is held in a socket 68 in lever 68, tending to move the outward ends of the levers .divergently. Lever 65 has a finger-pad H and lever 68 has apad 18, these being located close together for convenient finger manipulation. Lever 65 has a ally from the damper 5|.

Spring 4! of the valve 34 acts through the valve, upper face of slot 42, lug 43, stem 44, and arm or lug 46 on lever 65, to normally hold thevalve 3'4 shut and maintain the outward end of the lever and the flnger-pad in an upward position, as in Figs. 1 and 3; and spring 61 normally maintains the outward end of lever 65 and its finger-pad ll in an upward position in relation'to lever 68 and its pad l8, and therear end 12 of lever 65 in relatively depressed position. Spring 6'! is of less strength than spring 4| so that when the fingerpad H is depressedwithout first depressing pad 18, the outer end of lever 65 will move down, and continue with lever 68, while the rear end 12 of lever 65 is moved to a position to cooperate with face 13 of the air damper, and thereafter further depression of pad ll will cause the lever 68 to be also depressed, to open the steam valve, as will appear. Spring 55 is of suitable strength and length to normally maintain the lugs or spring seats 54 and 56 in their most separated positions (Fig. l) and thus to move lever 58 to a position relatively close to the face of the damper (in an angular direction) .as also shown in-Fig. 3, and also to allow for substantial relative angular movement of the lever and the damper in their various operations, as will appear.

For the initial operation, pad 18 of the lever GE) is depressed, without depressing pad ll, so that the levers retain their normal relative positions. Lug or arm BI is thus moved clockwise in Fig. 3 and acts on lever 58 to move it to position v of Fig. 2 and in this movement the lever acting a through spring moves the damper 5| to closed position, thus closing the passage. substantially before the valve 34 is opened; and upon further depression of pad 78 the arm or lug 46 of lever clockwise direction, this further movement of lever 58 after closing of the damper being permitted by compression of spring 55. It will be noted in Fig. 4 that in the stated extreme downward position of lever 68, when its pad is depressed without'depression of the pad H of lever 65, the latter remains. in relatively elevated position, held so by spring 6?, and the rear end 12 of the lever does not contact with flange 13 of the damper, permitting the damper to remain in closed position and preventing any access of fluid to passage 48 and the Venturi tube. ing been opened in the manner described, fluid or steam under desired pressure is discharged from nozzle 3!, through the tubular passage of the valve body to the distributing chamber.

The valve 34 hav- 7 I may then supply'to the distributing chamber I a mixture of fluids, with a propulsive effect. This is done by opening the valve 34 or allowing it to remains open while the damper 53 at the same time is opened or remains open if it has not previously been closed. 1 The desired valve operations may be effected by different modes of manipulation of the levers. Thus, if the lever remains in fully depressed position, as in Fig. 4, to open the damper 5i and supply the mixture, it is only necessaryto shift one finger to pad H of lever which then moves to the position of Fig. 6, elevating the rear end 12 of the lever into contact with the flange face 73 of the damper and opening the damper, as alsoshownin Fig. 5, spring 55 being in this case fully compressed. 4

If the passage 48 communicates with the atmosphere, when the parts are in the position of Fig. 6, air will be drawn through port 49' by the injecting action of the steam jet and will be admixed in throat 32a as explained in my said application. Obviously, if the passage 48 communicates with a source of supply of moth-proofing or moth-repellant compound, then the compound willbe drawn in and projected with the steam to saturate garments or fabrics beneath plate I5. 7

If just previous to the application of the mixture, the levers are in normal or idle position. as in Fig. 3, with the valve 34 closed and the damper open,.to supply the mixture it is only necessary to depress pad II of lever 55. As the pad moves down to the level of the other pad I9, as shown in Fig. 5, with the forward portion of lever 95 engaging on lever 69, the rear end I2 of lever 65 is raised to engage flange 73 of the damper which is thus held open, while further depression of pad II causes full depression of lever 69 and the opening of valve 34 while the damper 5| remains open, the parts then being in the position in Fig. 6.

After the mixture has been supplied for the desired time, the levers are permitted to return to normal position, shutting off the supply through valve 34.

I wish it to be understood that the invention is not limited to the character of fluid which flows through nozzle 3| to create the injector action, nor 'to the fluid drawn through passage 48 for admixture with the first fluid.

In Figs. LIL-there is shown a modification in the invention wherein the means controlling flow of steam, and air, are separately operated, and also provision is made for the admixture of other fluids with the steam, such for example, as a moth-proofing composition. The tube 89 of the casing is screw threaded at its lower end the same as the tube 2i of Fig. 1, and is also provided with a Venturi passage 8 I. The steam passage 82 corresponding to the passage 21 of Fig. 1 extends upwardly and communicates into a chamber 83 in the casing proper. The outer end of the casing 83 is closed by a plug 84 provided with a central recess 85 which receives the end 89 of a steam control valve. The plug 84 is also provided with an annular groove 97 in which is seated a coil spring 88 which exerts a pressure against the valve head. A washer 89 is seated in the outer end of the valve head and is held in place byscrew 99. The washer is of suflicient diameter to cover the end of the annular flange or ridge 9I around port 92 separating chamber 83 from chamber 93. A packless valve stem 94 engages at one end the head 95 of screw 99, said head being located in the port 92 and being slabbed in cross-section to establish communication between the chambers 83 and 93, when washer 89 is moved away from port 92. The valve stem is mounted through a sleeve or gland 99 having screw threaded engagement at 91 with one wall of the valve casing and at 98 with another wall of thevalve casing.

valve casing. The forked arms of the lever I94 of a lever I32, as shown clearly in Fig. 11.

are provided withcams I 96 against the lower side of which the forward arms I91 of the bell crank 99 bear. Obviously, depression of the lever I94 from the dotted line to the full line position of Fig; 7 rocks lever 99 and forces the valve stem 94 and screw head 95 inwardlyremoving the washer 89 from the port 9I establishing communication between the passage 82, chamber 83 and chamber 93, so that the steam may flow through the said passage, chambers and port, and downwardly through the jet I99, and then through the Venturi escapement.

In the case of garment pressing machines, the steam would flow from the Venturi tube into the tube 8I to the source of,

pressing head, and from the head through the garments into the buck. To facilitate dispersement or distribution of the steam throughout the head, I provide a conical member H9 at the lower end of the Venturi tube and connected thereto as by means of a pin III extending through the tube and the member II9. Obviously the steam, or admixed fluids as presently described, issuing through the Venturi tube, will be dispersed as they pass the curved surfaces of the member H9 in the space between the member and the lower end of the Venturi tube.

The Venturi tube 8| communicates at its upper end adjacent the jet I99 with a passage II2 leading down from the chamber II3 through which. the valve stem '94 and its surrounding sleeve 96 are mounted. The top of the chamber j H3 is formed by tubular extension II4 on top of the valve casing proper, and the exterior of the extension H4 is provided with ridges H5 at between the inturned lower end II! and the top of the cap, is a. felt lining I2I. As shown clearly in Fig. 10, there are spaces I22 between the ridges H5 and the walls H4 and lining I2I. Within the cap I I9 is a plate I23 connected by a rivet I24 to a'stem I25 which is mounted through a bore I25 in the top of the cap. ',To'the lower face of the plate I 23 is attached a felt disc I21, as by means of rivets I28.

There are spaced projections I29 on top of the cap. Apin I39 is mounted through the stem I25 and through the space between the projections I29 and also through the opposite arms I3I Cotter pins I33 are shown retaining the pin in place.

The lower ends of the arms I3I are formed with V cam surfaces I34 to bear against the top of the cap IIB.

When raising the felt disc I27 fromthe top of the extension I I4, the handle of lever I32 is raised from the dotted line position of Fig. 7 to the full line position thereof, which causes the cam surfaces I34 to bear against the top of the cap II6, so that the pin I39 is moved upwardly drawing the stem I25 upwardly against the ac.-

tion of the spring I35, which is located in the bore I26. When the lever I32 and stem I25 are thus moved upwardly, the disc I2'I is raised from I contact to the extension II4, so that with the action, chamber H3 and openings I22 tofbe admixed with the steam at the throat of the Venturi tube and projected therethrough. However when the lever I32 is lowered, moving the cam surfaces I34 from binding'engagement with the top of the cap, the stem I and plate I23 are also lowered, so that the spring I35 forces the felt disc I21 tightly against the top of the extension I M, so that no air can be drawn through the passages I22 into the chamber H3; The closed position of the air'valve is shown in Fig. 9. I also'moun't a pin I36 through one of the extensions 529 for engagement by the lower ends of the handle I 82, to force the cap down in case of friction in the felt disc, or in case the spring'I25 should break.

I have shown a tube I31 mounted through one of the walls of the valve casing proper and communicating into the passage H2. The other end of this tube may be connected to a source of supply of moth-proofing compound or other liquid, not shown. When the tube 531 is so conneoted and when the parts are in the position of Fig. 8, the s'teamfissuing through the jet I639 will draw the air through the passage are in the position of Fig. 9, the steam issuing 1 through the jet liiil will create a suction in the passage H2 drawing the moth-proofing compound through tube I 31 for admixture with the steam and who sprayed on garments orfabrics.

The steam pressure or velocity drives the admixed steam and air or steam and the air would otherwise directly contact, with the soft fibrous or felt covering, the hissing sound is very materially deadened. l
